4-month-old male cat.Grey zone LVH m mode, some 2D measures exceeding 0.6mm.SAM present with MV regurge. Ischemia/fibrosis in RSA view with a couple B lines I don’t think significant? LAD=normal,RSALA:AO= mild increase.Brief follow up echo to complete with cat fasted and sedated. Similar findings; increased HR and more significant LVH(0.7cm) than earlier study. Mitral E:A…

Diastolic dysfunction and heart rate
2 1/2-year-old spayed cat. Required butorphenol sedation. It had a mild effect. Heart rate rarely went below 200bpm. Cardiac measures were WNL. Mitral inflow was evaluated with pulsed Doppler, with the sweep speed increased to discern the E and A waves. The heart rate noted on the ECG is not correct on that picture. IVRT…
